Create the new 2D profile shape. Determine the generic shape and parameterization best suited to the required profile.
At this point do not include Cardinal Point Plines in the Pline set, just place other Plines you will find useful and name them accordingly. Do not include any Plines with the special PKEY values as these will be added in the upgrade process. Build the new catalogue, recording which parameters apply to which dimension.
In AVEVA Bocad Steel create the profile such that its default orientation will be the same as that in the base product when laid out from start to end.
With predefined profiles, such as unequal angles, the default orientation may be different. In this case, you may need to use mirroring and/or rotation transformations to get to the correct "starting position". Mirroring represents a transformation about the Y axis: rotation is about the Z axis, following the "Right Hand Screw Rule". Keep a record of these necessary transformations as they will go into the orientation mapping file.
On the 2D profile in each package locate where the Cardinal Points and their Pline equivalents will be. In the PARAGON module, place any other Plines that you may find useful. Record the correspondence between Cardinal Points and Pline names. Remember also that any mirroring and rotation will affect the Cardinal Point locations.
Note:
The coordinate system in the base product is right handed, whereas in the neutral
file it is left handed. The Cardinal Point : Pline equivalencing by superposition
is illustrated above for an unequal angle profile. Using this kind of diagram you
will be able to determine the mappings between Plines and Cardinal Points.
If the new profile is not one of the existing shapes, you may need to assign a new profile integer shape code to it for use in the profile mapping file.
Also, if the new profiles are for a new country standard, you may need to assign a new country code to this. This country code abbreviation is stored in the internal steel standards file. This abbreviation is also used in the profile mapping file.
